But lest the men who doubt this should, with similar scepticism, refuse to accept as true what is written concerning the first man's creation, let them inquire or observe, if they can at least believe this, how numerous are the species of animals which are born from the earth without deriving their life from parents, but which by ordinary procreation reproduce offspring like themselves, and in which, notwithstanding the different mode of origination, the nature of the parents born from the earth and of the offspring born from them is the same; for they live alike and they die alike, although born in different ways. There is therefore no absurdity in the statement that bodies dissimilar in their origination are alike in their resurrection. But men of this kind, not being competent to discern in what respect any diversity between things affects or does not affect them, so soon as they discover any unlikeness between things in their original formation, contend that in all that follows the same unlikeness must still exist. Such men may as reasonably suppose that oil made from fat should not float on the surface in water as olive oil does, because the origin of the two oils is so different, the one being from the fruit of a tree, the other from the flesh of an animal.
